VAT number forgotten when ordering?

If you have already ordered and paid for KNX products / services, but you have forgotten to enter your VAT number and you are eligible for VAT exemption, then there is a possibility to have a refund of the VAT difference.

There is however an administrative fee of minimum 50€ that will be charged for correction of the bill, issuing of a credit note and refund of the paid VAT. If you wish to be refunded, please contact us.
